Introduction
BRAVO30X is a computer capable of controlling distribution of
chemical products on sprayers equipped with valve control unit
from 1 to 5 section valves. It is composed of a control panel, to
be kept within the operator's reach, allowing control of all the
valves.
BRAVO30X can also operate in manual mode; in this case the
litres/hectare adjustment is made using the adjustment keys.
If necessary, it is possible during automatic spraying to adapt
delivery to treat aread of concentrated growth, temporarily or
increasing or decreasing the dosage by ±50%.
The large display of the BRAVO30X allows the operator to keep
a constant eye on all data relating to the operation in progress,
e.g. speed of the vehicle, the litres/hectare sprayed, total
surface area treated and the quantity of liquid sprayed.

The sensor (S) detects the speed of the tractor by means of
the magnets (C) and at the same time sends the data to the
flow-meter (F) and/or pressure trasducer (M) so that the
control panel (A) can handle the control unit.
BRAVO30X has a large backlit multifunction display on which
the user can display all the data defining the treatment in
progress.
6 function keys at the side of the display allow the user to view
and set the distribution parameters on the display, together
with the other keys on the panel.

User Programming
Introduction
Before starting treatment, some settings are necessary to
inform the BRAVO30X about the characteristics of the vehicle
on which it is installed (by means of the wheel constant), the
characteristics of the liquid distributed (by means of the
density), the type of flow-meter connected and the type of
nozzlefitted.
Calculating the wheel constant
It may be necessary to change the wheel on which the speed
sensor magnets are installed, or the vehicle on which the
sensor itself is installed, meaning that the circumference of the
wheel changes.
In this case the constant on the BRAVO30X has to be changed
to allow it to measure the distance travelled correctly, and thus
make a correct calculation of the quantity of liquid delivered per
unit of surface area.
The wheel constant is the distance the vehicle travels for each
pulse received from the speed sensor.
The following is the procedure for calculating the wheel
constant:
Measuring the distance travelled in 10 turns of the wheel the
speed sensor is installed on (with the tyres inflated at working
pressure).
This is the formula to calculate the wheel constant:
Space travelled (m) x 10
= —————————————
number of magnets
Example:
- space travelled in 10 turns of the wheel = 25.4 m
- number of magnets installed = 10
The wheel constant is:
25.4 x 10
= ———————— = 25.4

10
Wheel constant menu
To modify the wheel constant, the user programming menu
must be accessed by pressing the key until the screen
shown on the left (menu 1.0) appears.
Manual setting
The key can be pressed to insert the value calculated for the
wheel constant directly: use the modification keys to change
and confirm the new value (the value set on the display is
25.40 cm/pulse).
Automatic setting
BRAVO30X is able to calculate the wheel constant automati-
cally, on the basis of the number of pulses received from the
speed sensor, when a distance of known length is travelled.
To carry out automatic the constant setting correctly, proceed
as follows:
1) Prepare the tractor with the tank 50% full
(the test can be carried out with just water ).
2) Drive the tractor to the start of the straight track of known
length and stop.
3) If the length of the track is different from that set, press
and use the modify keys to enter the new value.
4) Press the key beside the word AUtO and drive along the
track.
5) At the end of the track, stop the tractor and press the key:
BRAVO30X calculates the wheel constant automatically and
shows it on the display.
N.B.: The test should be carried out on ground of medium
hardness. If distribution is on very soft or very hard ground, the
difference in wheel diameter may lead to a difference in the
wheel speed reading, with a consequent error in calculation of
the distribution.
In this case, the wheel constant setting procedure should be
repeated.

Variation of the density factor of the product delivered
When distributing products other than water (e.g. liquid fertilis-
ers) the values read by means of the blade or turbine flow-
meter may be inaccurate, causing errors on distribution. To
overcome this problem, it is possible to modify a density factor
which acts as multiplier on the values read by the flow-meter.
N.B.: The ARAG ORION model flow-meter is unaffected by this
problem.
Density factor programming menu
This menu is accessed from the main display screen by
pressing the key for one second.
Use the keys to locate on menu 3.0 shown on the left.
To modify the value of the density factor, press and use the
modification keys (in the example, the factor is 1.00 ).
Press to confirm the value and exit or to exit without
modifying.
Automatic density calibration
The automatic density calibration procedure is carried out as
follows:
1) Fill the tank with a known quantity of water
2) Reset the field data (page 14)
3) Distribute the product (page 16)
4) Calculate the amount of liquid distributed
5) Press to access the programming mode
6) Select menu 3.0
7) Perform the calibration
Calibration is started by pressing the key beside the word
GAL (fig.8).
The screen shows the amount of liquid counted by the compu-
ter (in the example 2546 litres) during the last distribution, with
the density value currently memorised.
Press the key beside the word rEAL, and enter the quantity
of liquid actually delivered during the treatment: the computer
will calculate and memorise the new density factor.

Modifying the nozzle data
Nozzle Flow-Rate
If the computer is not connected to a pressure transducer, it
may still be able to calculate and display the pressure on the
basis of the flow-rate value measured by the flow-meter and
the nozzle flow-rate data.
N.B. For correct pressure measurement, the nozzles must be
in good condition, so that the real flow-rate is the same as the
rated flow-rate.
If the operator is using nozzles which do not correspond to the
ISO standard, he can modify the default settings of the eleven
preset ISO nozzles.
This menu is accessed from the main menu screen by
pressing the key for one second.
Use the keys to locate on menu 4.0 (fig.10).
As can be seen, nozzle number 5 (red colour ISO 11004) is set
to deliver 0.8 litres/minute at a pressure of 3.0 bar. The opera-
tor can press the and keys to modify the flow-rate and
pressure value as appropriate to the nozzle in use.
To restore the ISO value, simply press the key and confirm
the values with the key.
See appendix for table 1, showing the relationship between
pressure and flow-rate for ISO nozzles.
Number of Nozzles
(467302 and 467304 versions only for 2- 4-way orchard
sprayers)
If the computer is installed on an orchard sprayer it is possible
to specify, according to requirements, the number of nozzles
used on each spray boom. By doing this the calculation of
pressure is more accurate if there is no pressure transducer
or the regulation is more stable if it is done referring to the data
read by the transducer.
You can access this menu from the main menu, press the
key for one second.
With keys go to menu 5.0 (fig.11).
Press the key and the keys to select the spray
boom for which you want to set the number of nozzles.
Press key to access data modification and set the number
of nozzles wanted by pressing keys .
Press to confirm the data and exit or to exit without
changing the data.

Setting the tank filling level
Before each treatment, the following operations should be
carried out:
1) Set the field number
2) Reset the field counters
3) Set the amount of liquid put in the tank
4) Select the nozzle to be used.
5) Set the distribution value.
Field number
BRAVO30X automatically records of the space travelled, time
worked, surface area treated and liquid distributed data.
BRAVO30X offers the possibility of nineteen partial counter
units (known for the sake of simplicity as fields), to which the
treatment counts can be addressed.
N.B.: Field number 0 contains the device's absolute counter
and cannot be deleted.
To set the field number, keep the field pressed until the
screen shown on the left appears.
The keys can be pressed to select the number of the
field; pressing confirms the number selected.
Pressing aborts the selection made and returns to the
main menu screen.
Resetting the field counters
The key can be pressed to reset the display of one or more
of the counters relating to the field currently selected; the count
selected and the symbol flash: pressing confirms the
reset, or pressing exits from the deletion mode.
N.B.: the counts relative to the symbols which are lit up are
reset (in the example in fig. 12, the space travelled, time
worked, surface area treated and liquid distributed counts are
reset). To change count, press .
Setting the amount of liquid placed in the tank
BRAVO30X is able to calculate the amount of liquid left in the
tank starting from the filling value and subtracting the liquid
distributed from it. The computer also warns when the liquid
level reaches the low threshold by sounding a beeper and by
flashing the tank level indicator light .
The amount of liquid placed in the tank is programmed by
pressing until the screen on the left is displayed.

Pressing the keys sets the tank level at the maximum filling
level envisaged by the manufacturer.
To set a level different from the maximum filling value, press
so that the liquid in tank value flashes and use the modification
keys to change it.
Filling the tank by means of the flowmeter
So the computer stores the exact quantity of liquid put into the
tank, it is possible to fill the tank up with the specific flowmeter.
To do this, access the filling up menu by pressing the key
on the main screen page until the screen page shown in Fig.
13 appears.
Now fill the tank up by starting the loading pump.
The computer shows in real time the quantity of liquid that has
been put inside the tank which is added to the liquid that is
already inside it, until the loading pump stops. (In the example
given in Fig. 13 there are 2,588 litres inside the tank).
Once filling up is finished, return to the main screen page by
pressing key .
Selecting the nozzle
The user will have selected the nozzle to be used for the
treatment on the basis of the speed at which the treatment is to
be performed and the quantity of liquid per hectare to be used.
This information is fundamental if using a pressure transducer
to regulate the distribution, but with a flow-meter alone, it is
only used to correct display of the pressure value calculated by
the computer (it does not affect the distribution setting).
Nozzle setting is begun by pressing the function key for one
second, until the screen shown in fig14 appears.
A flashing symbol appears in the bottom of the screen,
indicating the type of nozzle selected (in the example, number
5).
The flashing symbol is underneath coloured indicators repre-
senting the standard ISO nozzle colours.
If the nozzle chosen is ISO, e.g. ISO11002 (yellow), simply
bring the flashing symbol above the rectangle of the same
colour (yellow) with the keys.
Press to confirm the new nozzle and exit or to abort.

Fig.18:
Setting the calibrated returns
If the operator wishes to use a non-ISO nozzle but still be able
to select the ISO nozzles directly, he can access a nozzle
known as "USER" in which he can set the data of the nozzle in
use.
To do this, display the nozzle selection screen as described
earlier and bring the flashing nozzle symbol into the posi-
tion (fig.16); the display will contain the indication of the
number of litres per minute delivered by the nozzle at a given
pressure (in the example, the nozzle delivers 0.70 l/min at a
pressure of 5.0 bar).
The number in the top left-hand corner indicates the distribu-
tion value (in litres/hectare) which the computer will maintain
with the nozzle selected. To change the last value set, simply
press the key and use the modification key.
N.B.: for each nozzle, BRAVO30X always sets the last distribu-
tion value used with that nozzle.
Valves with calibrated returns
If the unit is fitted with valves complete with calibrated return,
and if BRAVO30X has been programmed for operation with
calibrated return during installation of the system, at each
nozzle change the flashing message rEG appears on the right
of the display.
This reminds the user that he has to perform a new procedure
to adjust the calibrated returns.
N.B.: The calibrated return adjustment procedure is necessary
to allow the computer to adjust and display the distribution
correctly when one or more section bars are closed.
Setting the calibrated returns
Setting of the calibrated returns is started by keeping the
function key pressed for 1 second (fig.18).
Open all the section valves and the master valve; the flow-rate
value currently read by the flow-meter (10.0 in the example) is
displayed beside .
Close the first section valve: the flow-rate information before
the closure is frozen on the display, while the flow-rate value
currently read by the flow-meter (with the section valve dis-
charging on the calibrated return), given by the sum of the flow-
rates to the boom and the tank, by means of the calibrated

Setting the litres/hectare to distribute
Prior to each distribution you first have to make sure that the
distribution set is correct: press until the value to distribute
flashes (Fig.20) and use the modification keys to change and
confirm the value.
Setting the distance between rows
(467302 and 467304 versions only for the 2- and 4-way
orchard sprayers)
In the case of the orchard sprayer versions 467302 and
467304 you will also have to set the distance between the
rows so that the computer can then make the correct
adjustments. By pressing the key followed by the
modification keys, you can select one out of the nine storable
distance values.
If necessary, it is possible to access modification of one of
these values by pressing the key and setting another value
by pressing keys and .
Press to confirm the data and exit or press to exit
without changing the data.
return is shown beside .
(In the example if fig. 19, this is 8.8).
At this point the calibrated return has to be adjusted so that the
two values are the same: when they coincide the section valve
can be reopened and the operation can be repeated for all the
other section valves.
Adjustment of the calibrated return is assisted by a beeper and
indicator lights; as the calibrated return approaches the
optimal setting, the intermittent sound emitted by the beeper
becomes quicker and quicker, until it becomes continuous
(setting OK). During the adjustment three flashing segments
indicate whether the flow-rate generated by the calibrated
return is too high or too low (in the example, it is too low).
Caution: the section valves must be closed one at a time: if
more than one section valve is closed simultaneously, the
display shows a dash in the position of the field; otherwise, the
number of the closed section valve appears.
Press to exit from the calibrated return setting procedure.

Start of treatment in the automatic mode
To perform a treatment in automatic mode, proceed as follows:
1) Check that the symbol in the centre of the display
has illuminated, or press the key so that it appears.
2) Open the section valves using the relative keys.
3) Go to the beginning of the field for treatment.
4) Open the master valve.
During automatic operation, BRAVO30X keeps the litres per
hectare applied constant at the value set previously.
The control keys can be provided to make a temporary variation
in the volume to be distributed (fig.21).
The display shows the percentage variation of the volume to be
distributed in alternation with the volume actually applied.
To cancel the temporary variation, return the percentage
variation to zero.
Treatment controlled in manual mode
To perform a treatment in manual mode, proceed as follows:
1) Check that the symbol has illuminated in the centre
of the display or press the so that it appears.
2) Open the section valves using the relative keys.
3) Go to the beginning of the field for treatment.
4) Open the master valve.
5) Use the control keys to modify the value of the amount to
be distributed (fig.21).
Attention: in the versions for the 467302 and 467304 orchard
sprayers it is also necessary to set the distance between rows
so the computer can display the correct data (page16).
Foam marker
If the foam marker kit is installed, the computer is able to
control it in 2 modes:
Manual mode:
Press the or keys to activate the side of the foam
marker required, and press the same key again to stop it.
N.B.: the foam marker is disabled automatically when the
master switch is closed.

Displaying the counts
Once the treatment is complete, the operator can consult the
data relating to it.
The counts made available by the computer are:
Space travelled (Km)
Time worked (hh.mm)
Surface area treated (hectares)
Liquid distributed (litres)
The counts refer to the number of the field currently selected.
When the and keys are pressed, the symbols illustrated
above appear beside the keys in succession.
The figure beside the symbol is the value of the count.
In the example in fig. 23, for field number 1, the distance
travelled is 253 Km, while the liquid distributed amounts to
2588 litres.
N.B.: the distance count only works with the master valve
closed. This count can therefore be used to measure the
distance between the field and the operator's home, or to
measure the length of a field.
N.B.: the time worked count can be stopped or started by
pressing the key.
When the count is enabled, the symbol flashes.
Consulting the treatment data
Automatic mode:
If the foam marker function has been set for automatic opera-
tion, the foam marker stops automatically when the master
valve is closed and restarts from the opposite side when it is
reopened.
The active side of the foam marker is indicated by the flashing
row symbol above the boom symbol (fig.22).
To stop the foam marker, press the foam marker key or
relating to the active side.
After a manual stoppage of the foam marker, next time the
master valve is opened the row symbols above the boom
symbol flash simultaneously to instruct the operator to activate
the side of the foam marker required.
